MUTOGRAPH.

[ all whom it may concern:

Be it known that I, FRANK C. NEWELL, a citizen of the United States, residing at Cleveland, in the county ofCuyahoga and State of Ohio, have invented certain new and useful Improvements in Mutographs, of which the following is a specification.

The invention relates to mechanism for reproducing and exhibiting symbols or in- 0 scriptions for advertising and other purposes, and particularly to that type of mechanism in which the symbols are formed and displayed upon a traveling band. The invention has for its principal objects; to produce 5 a mechanism of this character in which the band employed may be used repeatedly and continuously, and is in fact indestructible; to provide a device in which the impressing mechanism consists of a single changeable.

mosaic capable of producing all of-the desired symbols whereby an exceedingly compact mechanism with a single set of operating means is secured; to provide a mechanism in which the motion of the band and the operation of the machine is continuous; to provide a machine in which the production of the desired symbols may be easily controlled from the key-board; to provide a display mechanism in the use of which all inks and coloring materials may be avoided; and to provide a stipple member capable of producing in relief on its face raised symbols applied in its back. One form of mechanism by which these and many other objects are" attained, is described hereafter as illustrated in the accompanying drawings, in which Figure 1 is a side elevation of the assembled device without the band;

Figure 2 is a front view thereof;

Figure 3 is a transverse section on the line IIIIII of Figure 1; Figure 3 is a view similar to that of Figure 3, but with the frame oscillated to its extreme position;

Stated briefly, the device com rises in its preferred form an endless belt or andnmeehanism in which the band is adapted to be carried past the reciproeable symbol or mosaic the device, upon whic plate whereby a series of characters are produced on the band. The mosaic plate is composed of relatively movable sections with operating means therefor whereby all the various symbols may be produced by a different arrangement of the sections comprising the plate. The variation in symbols is produced by means of a rotary adjustable member or selector as it will be called, which selector in its various positions is adapted to show on its face in relief the various symbols impressed on its back by the mosaic plate and is made to pass the mosaic plate by means of a rotating turret constituting a part of the mechanism over which the band passes, and which in effect constitutes one of the sprockets for the belt, the other sprocket for the belt bein an idler. The space intermediate the sproc ets constitutes the portion exposed to view and the signs are read as produced on this exposed portion.

As shown then in assembled form in Figu-res 1, 2, 5, 12, and 13, the principal parts of the machine are the endless display belt A (Figures 5, 12, and 13,) supported and operated by the turret B at one end thereof which acts as a drive s rocket, the mosaic plate C made up of a p urality of movable sections from which all the symbols are to be formed in relief, and adapted to be moved a ainst the belt, the selector D which contro s the bars which operate to produce the various sets of sections in the mosaic, and by whose ad'ustment rotarily all of the desired symbols may be produced, the key-board E which controls the selector D to bring itinto position to produce the desired symbol in the mosaic, and the carrier F for the mosaic plate C which is adapted to be reciprocated to carry the stipples against the belt, and a supporting frame G for the carrier and selector ,which is adapted to be given an oscillatory motion in the direction of travel of the belt, when it en ages the belt to give its impression, and t e main supporting frame H for all the other mechanism is sup orted.

Referring 'rst to the band carrying mechanism, it will be seen from Figures 1, 12, and 13, that the turret B constitutes one of the band sprockets, while the idler member 22 constitutes the other sprocket, between which the endless band A is carried. The drive for the band is the turret B, which as shown in Figure 1, consists of a spider frame 23 provided with depending arms 24 adapted to engage the belt, and supported pivotally on the shaft 25 carried by the arm 26 of the stationary frame H. The driving mechanism for the turret includes the drive shaft 27 connected to a continuously operating motor (not shown) and the gears 28 and keyed to the shafts 27 and 25 respectively. The band itself, together with the means for engaging and guiding it will be described hereafter in detail.

One of the principal features of the device is the mosaic plate C for impressing the symbols upon the band shown clearly in Figures 2, 5, 7, 10, and 11. As shown here, the surface of the plate is divided into a plurality of mosaic sections reciprocably supported in a frame 30, and each supported by pins 31 provided with springs 32 normally intended to force the section to its rearmost position. By allowing certain of these pins to be operated by the springs to force them back the other sections may be allowed to stand out in relief, forming .the desired symbol. In

Figure 5 all of the sections are held in their forward position and the front of the plate is smooth, while in Figure 7 which indicates the plate at the time it engages the belt, a part of the pins have been allowed to fall back, thereby leaving a symbol on the face of the plate, which in the present instance is the figure 5, shown in Figure 2. As shown, the plate is divided'into about sixty sections, by which all the letters and the numerals up to 9 may be produced in the block style. It has been a matter of considerable difficulty to arrange the sections in proper shape and size to produce all desired combinations, but the manner in which it is accomplished will be apparent without detailed description, by an inspection of Figures 2 and 10, in which the manner-of securing the figure 5 is indicated. It is of course clear that other mosaics might easily be designed with different styles of letters and with other symbols than letters and figures, the arrangement shown being preferable,- however, because of the simplicity and clearness of the block letters. The mosaic plate must necessarily be reciprocated bodily to impress the raised symbol on the band A, and in order to accomplish this result the oscillatory frame-work F is provided (see Figure 5.) This frame-work is pivoted to the frame-work G at 34 and comprises an upper portion carrying the parallel plates 35 and 36 in which the pins are slidably mounted, and the depending arm 37 to which is attached the actuating arm 38. The arm 38 is actuated by a cam 39 on the drive shaft 27. The actuating arm is revided with an antifrictional roller 40 w ich I engages the cam groove 41 (Figure 6). groove is so shaped that the mosaic plate is gradually advanced until it engages left of the center of gravity of the frame F.

It will be seen that the plate is reciprocated to engage the band at each revolution of the shaft 27. There is also mounted upon the oscillatory frame F a set of bars 42, 42, 42", etc., for engaging the pins 31, and the rotary selector I) which governs the production of the symbols on the mosaic, which bars and selector D will be more particularly described hereafter. In order that there may be no stop of the band necessary in order to allow thesymbols to engage the band, means are provided for oscillating the mosaic plate about a vertical axis, whereby at the moment the symbol engages the belt it will be moving in the same direction and at the same speed as the band, and whereby the mosaic plate will return to its starting position after it engages the band. This result is accomplished by mounting the reciprocatory frame F upon the frame G pivoted on the trunnion 43, which frame G is oscillated from the drive shaft 27 by means of the cam 44 (see Figures 3, 4 and 5), keyed to such shaft and engaging the rolls 45, which rolls are mounted on the slide 46, guided as indicated, in an oblique direction. Connection is made between the slide 46 and the frame G for oscillating it, by means of the arm 47 pivoted at one end at 48 to the slide, and at the other end at 49 to the arm 50 on the frame G. It will be seen from the foregoing that means are provided for oscillating the mosaic frame laterally and for giving it a motion transversely to the belt.

The means of controlling the desired symbol for the belt will now be more particularly set forth. This controlling means comprises two mechanisms,namely, the bars 42, 42, 42, etc., and the rotary selector D. The bars are all pivoted'to the frame F by the rod 51,-and engage the cross members 52 (see Figures 7, 10 and 11) on the rear ends of the pins 31, while the selector D is rotarily mounted on the rod 53 carried by rigid arms 54 which constitute a part of the frame F, and engages the rear of the bars 42 42, 42", etc. in such a way that at the various points .of its rotary adjustment it will allow different combinations of bars under the influence of the springs 32 to be pressed back. As indicatcd in Figure 8, the selector D is built up of a plurality of large disks 53 with interspersed smaller ones 54', thereby forming ots for the reception of the rear of the bars 42, 42, 42 etc. The smaller disks 54 against which the backs of the bars bear are provided with notches 55 (see Figures 5 and 7) into which notches the projections 56 on the backs of the bars are adapted to fall when the selector is turned to the proper extent. When the selector is turned to the proper position so that its notches are in position to engage the desired projections 56, the frame F and actuating bars are moved toward the band A by means of the cam 39 and the arm 38, and those bars having the projections in place to engage the notches fall to the rear of the other bars, whereby the mosaic sections connected to such other sections are left in relief and constitute the symbols, and the plate advanced-bodily to the osition of Figure 7. In order that the scector may be turned freely in coming to its desired position it must of course be disengaged from the projections 56 on the bars, and in order to accomplish this the stop 57 is 80 provided This stop comprises a bent strap pivoted at 51 and adapted to engage at its upper end the shaft 25 and the backs of all the actuating bars, and prevent any further movement backward of such bars. As shown in Figure 5, the frame F with the sclector D is in its rearmost position, in which position the selector isto the rear of and disengaged from the bars 42, 42, 42", etc., and is free to revolve in any desired position. As shown, the selector has an operative surface extending around about 1S0, and this 180 is divided into fractional parts so as to produce all the letters of the alphabet and the numerals at some part of the segment. For convenience in operation it is desirable to have the selector return to a predetermined position after each actuation, and to accomplish this I provide the shaft 53 with a pair of cranks 59 and 60 at either side 0 of the selector, at an angle of 90 to each other, and secured thereto are the springs 61 and 62 which will normally bring the selector after each operation, so that the central part of the operative 180 segment is ad- 5 jacent the projections 56 on the backs of the actuating bars, at which position the selector is so notched as to receive the projections 56 on all of the bars, and as all the bars may fall back no symbol is produced on the mo- 0 saic plate. It will be apparent from an inspection of the mosaic plate that a very compact arrangement of operating mechanism is necessary, and in order to illustrate clearly the way in which the actuating bars for the 1 5 various sections are arranged to secure such compactness, I have shown in Figure 10 a diagrammatic view of the sections of the mosaic, including the cross pieces 52 secured to the ends of the pins 31, and the actuating 1 0 bars 42, 42, 42", etc. The actuating bars are adapted to engage the cross pieces 52 at portions of their length and are notchedto clear such cross pieces 52 at other portions of their length. For the sake of illustration I have shown those portions of the actuating bars which engage the cross pieces, insection, A and the notches on such bars in dotted lines.

By the use of the cross pieces 52 a single bar as 42 can be made to operate a section of the which keys are.

' keys.

mosaic, not in line with it, and a section may be operated by any one of a number of bars. By cutting the notchesin the actuating bars it is possible to top of the mosaic without operating the lower ones, and to operate two sections in line vertically without operating intermediate sections. Figure 11, which is a sectional view, shows the manner in which the various bars engage the cross piece 52 while certain other bars pass such bar without engagin 1 by reason of the notches. It is thought fiat the arrangement and principle will be clear without a detailed descri tion of the operation to secure the variousl trate with the figure 5 shown on Figure 2 of the drawin it may be stated that in order to form such gure 5, the bars marked a; in Figure 10 have their projections 56 engaging in the notches 55 in the selector whereby such bars and the sections supported thereby by means of pins 31 drop back, leaving all of the other sections in relief to form the figure 5.

Another important feature of my invention is the keyboard control whereby the selector D may be made to rotate to the osition to produce any desired symbol. The selector may be connected for operation, from the keyboard a number of ways, but in the present instance I prefer to utilize the lateral oscillation of the frame about the center 43 to oscillate the selector, for which pur ose the cranks 59 and 60 are provided with forwardly extending connecting rods 63 and 64, which rods are connected to the key engaging means and 66 adapted to be engaged by the lower part of the key, pivoted to the stationary frame H at 65. As shown in Figures 2 and 3, the ke board is divided into two sections, and the keys of one section are adapted to operate the connecting rod 63, and the keys of the other section to operate the connecting rod 64. The connecting rod 63 with its half of the keyboard operates the selector from the center of the operative 180 segment to one extreme of the segment, and the other arm 64 and its keyboard section operates the selector through the rest of the segment. The setting of the selector D occurs during the swing of the frame G about its center 43 as it moves from the position of Figure 3 to that of Figure 4. The connections whereby the keyboard actuates the connecting rods 63 and 64 are shown in Figures 1 and 5, and as here shown the connecting rods are secured to the cranks 59 and 60 by means of universal joints, and also to the key engaging members 65 and 66 by similar joints. Describing first the side of the keyboard shown in Figure 1, it will be seen that the member 65 is pivoted at 67 and carries at its top an engaging hook or ledge 68 adapted to be enga ed by the lower projection on the actuate the sections at the etters, but to illushe keys are normally held up by each a different distance from the selector,

and when the ledge 68 engages the various key points during the swing of the oscillatory frame, the selector will be rotated. The distance between the selector and the various keys is such that when the key is operated the selector will be rotated the proper distance to bring the notches on the selector in position to produce each letter on the mosaic plate. The other side of the keyboard is similarly arranged, with the exception that the hook on the key engaging member 66 and on the keys is reversed, which is necessary in order to turn the selector in the reverse direction during the backward oscillation of the frame G. The key engaging member and the key points are so curved that they will not engage when the parts are moving in the wrong direction, whereby all danger of accident is avoided in case the-keys should be pressed down on the wrong side during the operation of the frame. It will be seen from Figure 3 that the engaging ledges 68 on opposite sides of the machine are moved to their extreme forward and backward positions respectively when thesupporting frame G is oscillated to its extreme position, and that the ledges are in position to engage any of the key points before the machine reaches its other extreme position as indicated in Figure 4. The springs 61 and 62 normally bring the selector to neutral position after each actuation, so that in no case need the actuation of the selector by the connecting rods be through more than an arc of 90.

In order to assure the positive positioning of the selector for each letter, I provide a supplementary rectifying device for assisting the springs 61 and 62. This device is shown in Figures 1, 3, and 9, and comprises a spring 71 secured to the arm 54 and having the recurved end 72 opposite the rim of the selector, which recurved end carries the pin 74. The rim of the selector is provided with beveled perforations 73 as indicated in Figure 9, and these perforations are arranged in such position that when engaged by the pin 74 in the recurved end of the spring-the selector will be in exact position for actuation. In order to cause the engagement of the pin with the perforations at the end of each stroke,a stop 75 (see Figure 3) is provided on the frame, which is adapted at the extreme end of the swing of the same to engage the end of the spring and force the pin into the hole 73 in the rim. By reasonof their tapering shape the holes 73 will bring the selectorto t proper osition. 7

now describe in detail the band 13 which I refer to use with the device as heretofore escribed. As previously set forth in connectionwith Figures 13 and 14, one end of the band is carried and driven by the turret B which acts as a sprocket, while the other end is carried by the idler sprocket 22. Intermediate of these two sprockets the band is inclosed by a casing consisting of a bottom member 76 and a top member 75. These members curve over the top and bottom of the band as indicated at 76', so that the edges of the band are concealed from view. The band which I use is ordinarily a heavy one and must necessarily be supported intermediate its ends, and for this faces projecting beyond the front of the belt.

The ends of these stip les are ,of a color contrasting to that of the alt, and when the ends of such stipples are forced out in any configuration they will show up clearly against the background of the belt. There is of course means for retracting the stipples not in use so that their faces lie back of the face of the belt and are concealed from view, so that all that is visible of the stipples are the ends of the projected stipples. The band may be a continuous flexible member, as for example a thick leather belt, but preferably I make it in sections or links each of which constitutes a stipple plate and is large enough to receive one symbol. The speed of the belt is just sufficient to provide one link for each actuation of the mosaic plate. It will be seen that when the plate is carried past an oscillating symbol in relief that those stipples opposite the raised portion of the symbol on the mosaic plate will be ressed forward and that such stipples will be proj ected from the plate in the form of the symbol impressed against the back of the plate, forming a letter in color contrasting to that of the belt. As thestipples are comparatively small it is found that the separate stipples are not observable, and that the effect produced is that of solid letters.

Figure 15 of the drawing illustrates the effect produced when the stipples are pressed through the plate, showing the letters F C N. A part of the face of the figure is broken away to illustrate more clearly the construction of the lates which are flexibly connected toget er. The plate consists of a metal framework 77, and an inclosed plate detachably secured thereto by means of set screws 78, and provided with transversely movable stipples. The plates are secured together in a flexible manner by means of pivots '79, and the engaging lugs are recurved as indicated at 80 in Figure 12, in order to fit the downwardly depending members 24 of the turret (see Figure 1). By the engagement of these members 24 on the turret a positive chain drive is secured for the belt, and the positioning of the plates comprising the belt is made accurate. The roller 77 which support the lower part of the belt are secured to the belt by means of arms 81 ro'ecting downwardly from the center of the ramework 77. The front of the band is composed of a series of plates 82, as indicated 1n Figure 15, which plates come togetherat their edges and project above the overhanging portion 76 of the casing 75 and 76. A smooth-faced belt is thus secured, the framework being secured by such plates 82, and a band of very neat appearance is thus secured. In Figure 17 a transverse section through the stipple belt is shown, on the line XVIIXVII of Figure 15. It will be seen from this view that part of the stipples are pushed out, thereb thereof, while the ot er stipples are so withdrawn into the band that these heads do not show from the front. This is more clearly shown in larger detail in Figure 18, in which the stipple member has the enlarged end 83 and the small shank 84, provided with a ball 85 to keep the stipples from being pushed through to the outside. The upper stipple is in exhibiting position, while the lower stipple is shown as shoved back, in which position the head, because of the shadow cast by the wall of the sti ple hole is partly visible from the front. I the plate is looked at at an angle, as from below, which is ordinarily the case in an exhibitin device, the head would not be visible at al The head of the stipple may be white and the band black, or this arran ement reversed by making the heads blac and the band white, the object being of course to make the sign as distinct as ossible.

11 Figure 19 I have illustrated another modification in which the form of the stipple has been changed. As shown in this figure, a very small stipple is used, and the head is made in the form of a wedge, which form is very desirable where a small sti ple is desired, and is intended to be rex liibited at short range.

In Figure 20 I have shown a preferred arrangement in which I use a composition framework for the stipple member. As here shown, thefront plate 82 is the'same as has been heretofore described, and the sti ple is the same, but the rear part of the p ate is made entirely different, in order to accomplish certain desirable results and functions.

exhibiting the ends Back of the plate 82 is a thin sheet of rubber 86, which sheet of rubber is slitted opposite the stipple holes, as indicated in the lower line of holes as shown in Figure 21, so that the stipple may be pressed therethrough as indicated in Figure 20, the flaps of the rubber being doubled back as shown, and when the stipple is withdrawn as indicated in the lower part of the figure, the flaps of the rubber spring back into place as indicated, thereby completely covering the end of the stipple. Means is thus provided whereby the stipple may be absolutely concealed when withdrawn into the body of the plate. The back of the body of the plate 87 is a resilient layer of material 88, preferably felt, whose object is to yieldingly engage the shank of the stipple and prevent any inadvertent.movement thereof either forward or backwardly before the proper time. A metal backing plate is provided, and intermediate this back and the layer 88 I provide a second flexible sheet of rubber 89 for engaging the head of the stipple. As an endless band is used, it will be apparent that means must be provided for pushing the stipples back into the plates before reaching the operating mosaic plate again. This may be accomplished in a variety of ways, but the simplest and most effective, and the one which I here employ, is shown in Figures 12 and 13, and comprises a resilient roller 91 which is adapted to be pressed tightly against the face of the stipple plate, and force the stipples back into the desired position. It will thus be seen that the stipple band is practically indestructible and may be used over and over again to produce clearly and accurately any impression impressed against its back by the mosaic plate. might easily be illuminated if desired, in order to use the device at-night.

The operation of my device is as followsf Power being applied to my drive shaft 27, such drive shaft is revolved and by means of the gears 28 and 29 revolves the turret B,

thereby carrying the endless band A about such" turret and the idler sprocket 22. The revolution of the shaft 27 also oscillates the mosaic plate by means of the cam 39 on such shaft and the connecting arms 37 and 38, thereby carrying such mosaic plate adjacent to and away from the belt by means of the shaft 27. Whenthe selector D is in neutral position the notches 55 thereof receive the projections 56 on the backs of the actuating bars and the springs 32. carry all of the sections of the mosaic back, so that none of them touch the stipple band Whenthe plate reaches its forward extreme. Simultaneous with the forward oscillation of the mosaic plate, the frame F which carries such late is given an oscillatory motion in the irection of travel of the belt, by means of the cam 44 on the shaft 27v which engages the It will also be apparent that the band ated, for the reason that the selector will be held in neutral position by the mutual action of the moving springs 61. If now the key .to .produce the numeral 5 is actuated (Figures 1, 2 and 7) such key will be pressed into the position shown in Figure 1, and while the rame G is oscillating laterally on its pivot 43 the selector will be turned from its neutral position because of the connecting rod 63 being held in the position indicated. At the end of this swing, by reason of the engagement just described,- the selector will be turned to the proper position to receive in its notches the projections on the backs of the bars marked as in Figure 10. At thesame time the end of the spring 74 will engage the stop 75, and the pin 74 will be forced into the tapering hole 73, thereby positively positioning the selector in the proper place. At this moment the frame with its mosaic late commences to oscillate forward away ii'om the stop 57, and the bars w'(Figure 10) because of the engagement of their projections 56 in the slots 55 in the selector can be forced back, thereby locking the selector in place, and causing the sections controlled by the bars which cannot fall back to stand out in relief, forming the figure 5. The figure standing out in relief will in the extreme forward stroke of the mosaic plate engage the stipple band, thereby driving forward the stipples in the configuration of the symbol and exhibiting such symbol on the face of the band. On the backward movement of the frame F and the mosaic plate, the parts, when they arrive in their rcarmost position, will be in position for a new operation, and the selector will have fallen back to such a position that it will be disengaged from the actuating bars and will have been returned to its neutral position by the operation of the springs 61 and 62. The parts are now in position for a new letter, and the operation may be repeated as before.

In Figures 22, 23 and 24, I have illustrated a modified arrangement of mechanism for returning the rotary selector to its neutral position, and also for holding it at its set position during the forward movement of the mosaic plate. This construction is in many respects preferable to the one heretofore described, for

the reason that it is more positive in action and no supplemental rectifying device is necessary for bringing the selector-to itsexact position. As shown in \Figure 24, the shaft 53 of the selector has keyed-thereto the part 92, which part 92 carries at its ends the rollers 93 and 94. Slidably secured over the shaft 53 is the member 95 normally pressed down by the spring 96. This member 95 is provided with a slot 97 for receiving the shaft 53, and has positioned transversely thereof the engaging member 98 adapted to bear upon the top side of the rollers 93 and 94. The member 95 is also provided with a plurality of holdingteeth 99 adapted to be engaged by the pawl 100 spring-held against 4 lector in position to roduce the desired symthe two-spring arrangement.

bols, as heretofore escribed with respect to the other construction. It will be seen that because of thespring 96 the selector when not otherwise controlled will normally come to the position of Figure 24, and thata rotation of the selector in either direction will cause the rollers 93 and 94 to raise the member 98 against the resistance of the spring 96. It will be seen that this arrangement takes the place of the two springs shown in the other construction, and that the selector will be brought to its neutral position more positively by the present construction than by The turning of the selector to its proper position for forming the desired symbol is controlled with the present arrangement by means of the keyboard and connecting rods 63 and 64, the same as heretofore described. The purpose ofthe pawl 100 is to hold the selector in its desired position until the letter or figure on the mosaic is impressed on the belt, after which the pawl is released, allowing the spring 96 to bring the selector to its neutral position. The release of the awl is secured by means of the engagement 0 the projecting pm 103 on the pawl with the stop 104. This engagement occurs just after the symbol has been impressed upon the belt, and as the frame drops back. The release of the teeth gives the selector time to return to its neunotches with the projections on the back of the bars is secured without the use of any additional rectifying means.

It will be apparent that the structure shown may be modified to a great extent without departing from the spirit of the invention as defined in the appended claims.

It is obvious that some form of band other than a stipple band might be used and that the mosaic might be modified to operate in any of the relations common to raised impressing symbols. It is also obvious that the plate is not limited to letters and figures but might be used with other characters. Means for operating the separate sections of the mosaic plate might also be arranged in other ways as the invention is of course not limited to a rotary selector or to the particular means for operating such selector. It willalso be apparent that insofar as the invention is concerned it is immaterial whether the ortions of the mosaic surrounding the symbol are retracted leavin such symbol in relief or whether the sym 01 itself is retracted leaving the surrounding portions of the late in relief, and the term relief as use in the claims is intended to-cover relie secured in both ways. All of these modifications would readily occur to one skilled in the art and could be easily worked into operative form. The stipple members are likewise capable of many uses other than the use indicated, and may be utilized in any case where it is desired to reproduce an impression in relief. It will be apparent that pictures might be effectively reproduced if the stipples were made small enough. My inventlon so far as this feature is concerned contemplates all uses of a structure in which relief impressions are produced on opposite sides of a plate by means of closely spaced movable stipples. It may further be stated that it is possible to make the stipples small enough to reproduce ordinary type, and on the other hand may be magnified to any desired size.
